Let's divide 20929275 by 809
Our goal is to divide 20929275 by 809.

Advancing to step 1:
If we divide 2 by 809, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 809

Going ahead to step 2:
20 divided by 809 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 809

On to step 3:
When dividing 209 by 809, we get 0 with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Append the next digit (2) from the dividend to 209 and continue with: 2092 / 809

On to step 4:
809 can be fit into 2092 2 times, resulting in a remainder of 474.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1618 from 2092 and we're left with 474.
Take the next digit (9) from the dividend and append it to 474, then repeat: 4749 / 809

Going ahead to step 5:
809 goes into 4749 5 times with a remainder of 704.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 4045 from 4749, we get 704.
Append the next digit (2) from the dividend to 704 and continue with: 7042 / 809

Step 6:
If we divide 7042 by 809, we get 8 and a remainder of 570.
Use 8 as the next digit of our solution. 
Result so far: 258.0
If we take 6472 away from 7042, we end up with 570.
Bring next digit (7) of the dividend behind the 570 and repeat the process: 5707 / 809

Let's proceed to step 7:
If we divide 5707 by 809, we get 7 and a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 2587.0
Deduct 5663 from 5707 and we're left with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 809

On to step 8:
445 divided by 809 is 0 with a remainder of 445.
The next digit of our result is 0. 
Result so far: 25870.0
The remainder is 445 after subtracting 0 from 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
809 can be fit into 4450 5 times, resulting in a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 25870.5
The remainder is 405 after subtracting 4045 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 10:
809 goes into 4050 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25870.55
Deduct 4045 from 4050 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 25870.55, with a leftover of 0.005.
